Software Setup; Silicon Laboratories Integrated Development Environment (Ide) - Silicon Laboratories C8051F064-EK User Manual

3.2. ADC Demo Software Installation
Install the ADC Demo application software according to the instructions below.
1. Place the Evaluation Kit CD-ROM into the PC.
2. An installation dialogue box will appear. Click the "Install Evaluation Kit Demos" button.
3. The Demos windows will open showing the available Evaluation Kit Demos. To install the application, click
the "C8051F064EK ADC Demo" button.
4. Follow the installation prompts to install the demo application. By default, the software will be installed in
the C:\Silabs\MCU\Demos\C8051F06x directory. In addition, shortcuts to the application will be placed on
the desktop and in the Start > Programs menu.
3.3. Running the ADC Demo Software
To run the demo, run the installed application. When executed, the following occurs automatically:
1. Firmware is downloaded to the C8051F064 FLASH code memory.
2. The C8051F064's 8051 MCU executes the firmware to configure the 16-bit ADC, direct memory access
(DMA) interface, and parallel interface to store samples in the onboard SRAM.
3. The ADCs sample a dc voltage (32,768 samples) to measure the inherent noise floor of the ADC and ana-
log front-end (AFE) circuit.
Note: There is also noise contributed by the circuit board, including noise from the USB connection to the ground on
the PC.
4. The ADC performs data conversions, and the DMA stores these samples in the onboard SRAM via a par-
allel interface.
5. Once the ADC samples are stored, the application reads these samples from the board (download through
the DEBUG USB port) and analyzes them.
6. The application displays a frequency analysis plot of the samples and shows their maximum, minimum,
and mean values and the standard code deviation or "sigma" (in LSBs) and calculates the dynamic range
based on a full-scale signal (rms) value. Such an evaluation is an important dc noise performance mea-
surement of high-resolution ADCs.

4. Software Setup

The included CD-ROM contains the Silicon Laboratories Integrated Development Environment (IDE), Keil software
8051 tools, and additional documentation. Insert the CD-ROM into your PC's CD-ROM drive. An installer will
automatically launch allowing you to install the IDE software or read documentation by clicking buttons on the
Installation Panel. If the installer does not automatically start when you insert the CD-ROM, run autorun.exe found
in the root directory of the CD-ROM. Refer to the readme.txt file on the CD-ROM for the latest information
regarding known IDE problems and restrictions.

5. Silicon Laboratories Integrated Development Environment (IDE)

The Silicon Laboratories IDE integrates a source-code editor, source-level debugger, and in-system Flash
programmer. The use of third-party compilers and assemblers is also supported. This evaluation kit includes the
Keil Software A51 macro assembler, BL51 linker, and evaluation version C51 "C" compiler. These tools can be
used from within the Silicon Laboratories IDE.
5.1. System Requirements
The Silicon Laboratories' IDE requirements are as follows:
Pentium-class host PC running Microsoft Windows 95 or later, or Microsoft Windows NT or later.
One available COM port.
64 MB RAM and 40 MB free HD space recommended.
5.2. Assembler and Linker
A full-version Keil A51 macro assembler and BL51 banking linker are included with the evaluation kit and are
installed during IDE installation. The complete assembler and linker reference manual can be found online under
the Help menu in the IDE or in the "SiLabs\MCU\hlp" directory (A51.pdf).
